Yes. I invented the Trie data structure when I was 19. It was very exciting finding out it had a name, and it was indeed considered a good fit for my use case.
Thats so funny, I had the exact same experience. And when I was 16 I "invented" csv's because I was too lazy to setup SQL for my discord bot. I like to think I've gotten better at searching for the correct solution to things rather than just jumping in with my best guess.
I was just going to say the same— LLMs are great for giving a name to a described concept, architecture, or phenomenon. And I would argue that hallucinations don't actually much matter for this usage as you're going to turn around and google the name anyway, once you've been told it.
